6 Claims. (Cl. 128224) My present invention relates to administering means adapted for use with pressurized units and is a continuation of my prior co-pending application Serial No. 6,400,,

filed February 3, 1960, now Patent No. 3,086,524 for Pelvic Cavity Treating Device and Medicament Therefor.

The administering means of my prior co-pending application is formed for effective pelvic cavity treatment, while the present novel applicator is formed for rectal cavity treatment in combination with standard pressurized units and valves now mass produced by the Aerosol Industry. The containers and valves used are optional. For example, the propellants used will determine the type of container and valve to be used and will also determine the particular formulation to be loaded in the container. Thus liquid propellants may require the usual dip tube from the valve, which valve is either metered or nonmetered as desired, or when the propellantis in the form of compressed gases the dip tube may be eliminated, but in any event as far as this invention is concerned, standard valves and containers are preferably used.

An object of this invention is toprovide a novel body cavity administeringmeans, whereby the same maybe coupled with standard aerosol units for treatment of the body cavities of humans or animals.

Another object is'to provide a particular novel coupling arrangement for connecting the novel administering means with the valve stem or the like of a pressurized container loaded with a prescribed'formulation.

A further object is to provide a novel manually actuated arrangement, whereby formulations in aerosol containers may be utilized in every instance wherein the old .type squeeze bulbs and the like were. heretofore used.

The foregoing and other objects and advantages of my present invention will appear more fully hereinafter from a consideration of the detailed description which follows,

in conjuction with the accompanying drawings wherein several embodiments of my applicator are illustrated. It

ing a coupled connection with standard forms of pres- .surized units one of which is shown with a thread coupling and the other with a non-threaded valve stem, such as are made in mass production for the aerosol industries by the valve and container companies;

FIGURE 2 is a plan view the countersunk valve actuating and formulation releasing portion of my applicator when used with a unit having a smooth exterior ice 2 surface on the valve stem as illustration of FIGURE 1A and such as usually is produced by the valve companies;

FIGURE 3 is 'a second embodiment of my applicator,

wherein a countersunk annular land or surface is used to actuate the valve means of the pressurized container and wherein the standard valve stem is modified with a flared or funnel-shaped outlet tip and a smooth outer diameter.

FIGURE 4 is a third embodiment of my invention, wherein the tubular injector is undulated in the provision of convex and concave portions with the perforations arranged at such concavo-convex locations.

Generally, the present invention comprises a novel combination of a novel administering means A with a cone portion B and a skirt C and a pressurized unit D, including a valve E adapted to be nested or housed within the confines ot the skirt of theadministering means in operative valve actuating arrangements as illustrated in the two embodiments of FIGURES l and 3.

Embodiment I (FIGURES 1, 1A and 2) The applicator A for one'typeof'valve stem, namely a valve stem 15 with coupling threads 16 thereon, has the cone portion B centrally formed with a threaded bore 17.

The threads 16 and 17 are complementary and a slight turn of the means A and the valve stem 15 of the pressurized unit D couples the' same together for actuating the valve E, .by means of a suitable hand squeezing arrangement comprised of finger engaging means 18 formed at the free exterior end of the cylindrical housing or skirt 12 and a finger'engaging surface 19 comprised of the bottom surface of the pressurized unit D, which projects from within the bore 13 beyond the free end of the cylindrical housing or skirt 12 a distance sufiicient to provide for slight relative telescopic movement in reverse directions, as shown by the arrows in FIGURE 1, of the administering means A with respect to the pressurized unit D. The resultant movement of the valve stem 15, which is picked up and moved therewith by the slight movement of the administering means A, thereby opens the valve E to discharge the contents of the pressure unit D into the injector 10. 7

Also, in the embodiment of FIGURE -1A, there is an alternative valve actuator means provided comprising a centrally apertured countersunk surface 20' formed in the face 21 of the base of the cone portion B, see FIGURE 2.

This alternative arrangement permits theuse of standard pressurized units having non-threaded valve stems 22,

- (see FIGURE 1A).

Embodiment II (FIGURE '3) A second embodiment of my applicator is illustrated in FIGURE 3 and shows a slight modification to the usual valve stem of a pressurized unit. For example, in using non-threaded valve stems and to provide for a rapid and spreadable discharge of pressurized formulation from the unit D, a valve stem is provided with a flared funnelshaped end 31. The rim 32 of the funnel end 31 of the valve stem 30 seats on a surface 33, and upon squeezing the actuator surface 34 and the bottom surface 35 of the unit D with the fingers of the users or operators hand the valve stem 30 is moved by the contacting surface 33 to open the valve E, thereby discharging the pressurized contents of the unit D into the injector 10.

Embodiment III (FIGURE 4) Operation The operation of the respective embodiments is basically identical, since the squeezing pressures applied by the fingers on the respective unit bottoms 19 and 35 and finger surfaces 18 and 34, are identical. For example, when the respective valve actuating surfaces are squeezed toward eachtother the valve stems 15, 22 or 30 are picked up by the fixed couple between the respective stems and the cone portions of the administering means, whereby the valve opens and discharges into the injector means I p 10 or 10'.

The valves used are well-known in the art and may be of any suitable standard type, such as illustrated for example in US. Patents 2,631,814 and 2,793,794 and British Patent No. 680,067. Thus pressure of the applicator A against the spring in these valves causes the same to unseat and allow passage of the container contents into the body cavity injector and thence to the parts of the body being treated.

Thus there is provided a novel pressurized system for 7 injection of many formulations to treat body cavities, wherein all old forms of squeeze bulbs and syringe devices are improved upon to the extent of makingthem obsolete.

Furthermore, by controlling pressures in the respective units used, that is, controlling the specific formulations with the particular propellants used, these units may be used to replace enema packages, suppositories and the like. For example, with such pressure and formulation controls, units in combination with the present novel administering means may replace suppositories and the like for infants with far more efiicient results and simplicity of application than heretofore possible.

From the foregoing, it is believed that the several uses and operational arrangements of my invention are clearly described, so that others skilled in the art can understand and practice the same if duly authorized to do so, and that when the term of this patent has expired the public may understand and practice the invention as described in the foregoing specification as summarized in the claims appended hereto.
